591-12-8 Usage

Chemical Properties

α-Angelica lactone has a sweet, herbaceous odor reminiscent of tobacco.

Occurrence

Reported found in grape, white bread, soy bean and licorice.

Uses

alpha-Angelicalactone acts as acancer chemopreventive agent. It is used in the synthesis of glutathione and the activity of glutathione-S-transferase and UDP-glucunonosyltransferase detoxification enzymes in esophagus, stomach, intestine, and liver. It is used in oral care formulations to round out mint notes and in coffee flavors.

Preparation

By dry distillation of levulinic acid

Taste threshold values

Taste characteristics at 100 ppm: sweet, creamy, coconut, vanilla hay and coumarin-like nuances

General Description

α-Angelica lactone, a cyclic lactone that occurs naturally in tobacco, is generally used in tobacco flavoring.

Biochem/physiol Actions

Plant-derived cancer chemopreventive agent. Increases the synthesis of glutathione and the activity of glutathione-S-transferase and UDP-glucunonosyltransferase detoxification enzymes in esophagus, stomach, intestine, and liver.

Safety Profile

Moderately toxic by ingestion andintraperitoneal routes. When heated to decomposition itemits acrid smoke and irritating fumes.

Check Digit Verification of cas no

The CAS Registry Mumber 591-12-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 591-12:
(5*5)+(4*9)+(3*1)+(2*1)+(1*2)=68
68 % 10 = 8
So 591-12-8 is a valid CAS Registry Number.

Renewable bio-based routes to γ-valerolactone in the presence of hafnium nanocrystalline or hierarchical microcrystalline zeotype catalysts

Antunes, Margarida M.,Fernandes, Auguste,Pillinger, Martyn,Ribeiro, Filipa,Silva, Andreia F.,Valente, Anabela A.

, p. 56 - 71 (2022/01/19)

Different renewable bio-based routes leading to the versatile bioproduct γ-valerolactone (GVL) were studied in integrated fashions, starting from furfural (Fur), α-angelica lactone (AnL) and levulinic acid (LA), in the presence of multifunctional hafnium-

Synthesis of renewable alkylated naphthalenes with benzaldehyde and angelica lactone

supporting information, p. 5474 - 5480 (2021/08/16)

Herein, we report a new route for the synthesis of renewable alkylated naphthalenes (ANs) with benzaldehyde and angelica lactone, two platform compounds that can be derived from lignocellulose.

Regioselective β-Arylation of α-Angelica Lactone through Isomerization/Addition under Mild Conditions

Zhuo, Kai-Feng,Yu, Shang-Hai,Gong, Tian-Jun,Fu, Yao

, p. 693 - 697 (2020/02/04)

The conversion of biomass-based platform molecules into various high-value chemicals greatly promotes the utilization of renewable biomass resources. Herein, an example of Rh-catalyzed β-arylation of levulinic-acid-derived α-angelica lactone was reported, providing the γ-lactone-structure products with high regioselectivity. Both arylboronic and alkenylboronic acids could be applied in this transformation. This reaction tolerated a variety of synthetically important functional groups. Moreover, the obtained γ-lactone products could be readily converted to high-value products such as 1,4-diols and γ-methoxy-carboxylates.
